Daniel Rivera was 21 when he was fatally shot on January 12, 2008, in Chicago. Reports describe his killing as a targeted shooting during a period of heightened violence in parts of the city, especially in neighborhoods affected by gang activity.

Rivera’s death was one of many homicides that year that underscored challenges investigators faced, including a lack of witnesses willing to come forward in several cases. The murder remains among Chicago’s unresolved killings from that period.

If anyone knew Daniel, his routines, or saw anything around January 12, 2008, please share what you remember.
